PIERRE, S.D. (AP) — A South Dakota judge has tossed out a voter-approved constitutional amendment legalizing recreational marijuana.

Voters approved the amendment in November despite opposition from Gov. Kristi Noem.

Noem’s administration supported a legal challenge from two law enforcement officers who argued that the amendment was technically flawed.

Possession of small amounts of marijuana had been set to become legal on July 1.
